I'm getting ready to lug a 325lb geothermal package unit up into the attic and wanted to see if there were any precautions I needed to take if I have to turn the unit on it's end in order to get it through some tight doorways. The most difficult part will be going from the second story to the attic stairway since it will need to be turned 90 degrees for a short time to fit through the doorway. The unit is a Tranquility 27 horizontal unit. I know that there is oil in the compressor and I am concerned that this may run out, ultimately shortening the life of the compressor. Is there anything that I can do in order to prevent any damage while transporting the unit to the attic? The unit will be able to rest in its normal position for at least a week before being turned on--will this provide enough time for the oil to drain back into the compressor? Thank you for your input.

Good questions that people a lot smarter than me will be able to answer.

Thought I'd comment WRT attic stairs.  Check that the stairs can handle the added weight.  Most will not.  Some installers will include as part of the project (and cost) replacing attic stairs with a heavy duty version when they know they're going to have to lug up the stairs a large GSHP unit.

Good luck!

Best regards,

Bill,

Thanks for the reply. Luckily the stairs that this will be going up are regular stairs--not the pull down type. I called Climatemaster and spoke with Keith who said that it "should be fine." I'm sure that he is right; I just like to hear from the community if they end up doing anything in particular to units that have to be rotated in such an extreme angle.
